vCenter Operations integration with vCenter Orchestrator

Hi,

I have integrated vCO 5.5 with vCOPs 5.8 and trying to call a workflow based on SNMP traps from vCOPs. The integration is fine but it's not calling the workflow as expected

I am following http://blogs.vmware.com/orchestrator/2013/04/vcenter-operations-integration-with-vcenter-orchestrator-in-5-minutes-or-less.html

Please help me to find out what is wrong.

Thanks!!
